Mandatory interventions needed to reduce salt

A University of Otago modelling study also found good results from the package of interventions introduced in the UK, where industry salt reduction goals have been set.Regulatory changes trump non-mandatory interventions such as voluntary food labelling and dietary counselling, the study showed.

The concept of a “sinking lid” to reduce the amount of food salt released to the national market to achieve an average adult intake of 2300mg sodium per day would be cost effective but was deemed a theoretical rather than realistic strategy, according to the authors.
